Follow-up Comment #1:

Reading the RFC, I think you're right about the options in ACKs - I've just
fixed that, thanks for reporting.

However, although it seems clear an ACK in REBINDING comes from a different
server (or else it would have been received in RENEWING), the RFC does not
speak of saving the server identifier from an ACK, it only says to save it
from an OFFER, which is what we do.

The result is (possibly intended by the RFC?), that once bound, a client
always first RENEWs to the original server instead of changing servers.

As it seems unclear to me, I'd rather not change it without knowing more.
